131 9809 Rear Axle Swap Tips - cylindrical Rollers - Photo 35150337

Bearings carry the weight of the vehicle whether the axle is a full-float or semi-float style. As a rule, the larger the axlehousing the bigger the bearings. Because they're usually stronger and more durable, cylindrical rollers such as these handle radial load well but not side loads. Tapered rollers are better for side loading and adequate radial load, while ball bearings seem to be the best all-around style. Custom axle ends can be installed on a housing to change styles, but the axleshaft must be a non-C-clip type to use tapered or ball bearings. If you change axle ends, you can eliminate some C-clip axles.
